Aurora Borealis (Northern Lights), Canada. April 2020

This is the first time I manage to film this phenomenon, thanks to the live stream provided by Polar Bears International/explore.org - wow! When fast moving electrons from the solar wind collide with oxygen and nitrogen in Earth's upper atmosphere, they give off a glow of colours (thank you, LL of Darkwater, for this explanation). Watch the live stream at    • Northern Lights powered by EXPLORE.org   Music in this video: Cassiopea, from the Youtube Audio Library.
